CHURN-COVER.

SPECIFICATION forming part of Letters Patent No. 380,832, dated April 10, 1888.

Application filed April 4, 1887. Serial No. 233,540. (Model) To all whom it may concern:

Be it known that I, JAMES H. TAYLOR, a citizen of the United States, residing at \Vestfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvementsin Ohurns, of which the following is a specification.

This invention relates to improvements in devices for securing the heads of churns to the body thereof, the object being to provide for churns having a removable head improved devices for attaching the head thereto; and the invention consists in the peculiar construction and arrangement of said head-fastening devices, as hereinafter fully described, and set forth in the claims.

In the drawings forming part of this specification, Figure 1 is a perspective view of the upper end of the bodyof a churn havingahead provided with fastening devices embodying my improvements. Fig. 2 is a transverse section of the central portion of the head of the churn and of parts of the fastening devices,the latter being hereinafter fully described.

In the drawings, A indicates one end of the body of a churn, said body in practice being of a barrel or keg form and belonging to that class of churns in which said body is hung on trunnions and adapted to be rotated for the purpose of agitating its contents.

The head-fastening devices of the churn consist of a metal center piece, 0, preferably of circular form, one edge of which is shown broken away in Fig. l to showapart ofa coiled spring thereunder, and said center piece is shown in crosssection in Fig. 2 through one of three horizontal lever-sockets z thereon and its raised central portion. Said center piece is cast from brass or malleableiron,andhas when cast two flat studs standing up on its upper surface, which studs are subsequently bent over to form the hooks m. Said center piece is perforated centrally to provide for placing it on the bolt h in the position shown over the central part of the metal frame f, and is provided with the aforesaid lever-sockets aacross each one of which is fixed a metal bar or rod, a. (See Fig. 2.) A coil-spring, J, is placed on the bolt it between the center piece,o, and the central part of the frame f. Three levers, K,have a hook engagement with said bars a of the three lever-sockets, a, one end of said levers entering said sockets, as shown, and the opposite ends of said levers pass through staples at the border of the head D and engage under the hooks y,secured to the outside of the churn-body, as shown. A toggle-lever, 10, having a bifurcated end,is pivotally connected to the upper side of the center piece,0,by hav' ing said studs thereon bent over to form hooks 00, as aforesaid, which engage with laterallyextending pivot-studs on the legs of said lever 10, one of which studs is shown in Fig. 1. Said toggle-lever is provided with two pivot-pins, 5, on its inner opposite sides, and a toggleyoke, E, of bifurcated form, is perforated, to permit of hanging it loosely on the upper end of the bolt h, its legs pending by the sides of the latter and having notches in their ends, as shown in Fig. 2, to engage with said pivot-pins 5 on the lever 10.

The nut s,placed on theend of bolt h,retains the yoke E on said bolt and forms an abutment for the upper end of the yoke,which is capable of such longitudinal adjustment on the bolt as the toggle mechanism consisting of the lever w and said yoke requires to make said mechanism operative to carry the center piece, 0, to the position shown in Fig. 1, when the toggle parts are brought substantially into line with said bolt, as shown in said last-named figure.

The spring J serves to lift up the centerpiece, 0, and the ends of the levers K, which engage therewith when the end of the lever wis swung upward, or to the position shown in Fig. 2.

When the end of the lever to is elevated, as shown in Fig. 2, the center piece, 0, is free to rise by the action of spring J, or to be lifted if no spring is used, and thereby the hook ends of the levers w, connected with said center piece, are so elevated as to cause the opposite ends thereof to lie freely on the border of the head D. While said toggle parts and levers are in the last-described positions, the head is put onto the churn, and being slightly turned thereon the ends of levers to engage under the hooks g on the churn-body. The end of the togglelever w is then swung toward. the head to the position shown in Fig. 1, thereby depressing the center piece,o,and the ends of the levers connected thereto, and causing the outer ends of said levers to engage with said hooks y, the border of the head serving as a fulcrum on which the levers K act, and hence the head is thereby forced against the end of the churn-body and remains there fastened until the end of lever to is lifted up as aforesaid.

What I claim as my'invention is 1. A fastening for churn-heads and analogous articles, consisting of the combination, with the head of the churn and with the hooks 3 on the body of the latter, of the center piece, 0, having sockets in its border, the levers K, having one end engaging in said sockets and the other projecting beyond the border of said head, the cam-lever w, pivotally attached to said center piece, the yoke E, engaging with said lever, and the bolt h, fixed to said head and passing through said center piece and yoke, and having the nut s thereon, substantially as set forth.

2. A fastening for churn-heads and analogous articles, consisting of the combination, with the head of the churn and with the hooks y on the body of the latter, of the center piece, 0, having sockets in its border, the spring J beneath said center piece, the levers K, having one end engaging in said sockets and the other projecting beyond the border of said head, the camlever w, pivotally attached to said center piece, the yoke E, engaging with said lever, and the bolt h, fixed to said head and passing through said center piece and yoke, and having the nut s thereon, substantially as set forth.
